Changing limits

I want some advice on changing the limit ...
I play poker from June 2009.A couple of months I started playing in the bankroll on PokerStars from September 2010.I play 1c/2c, I started with $ 8 from one freeroll and going well(i think) ... but when I try to exchange the limit,i lost a lot and again back to 1 / 2.
i will also provide you a screenshot to give you an idea?
What do you thing about it, what do you think about Leak Buster, I analyzed the game and if I did what they told me I lost the worst!Leak Buster's advice are for bigger limits,wright?Not for 1c/2c
You can analyze and other statistics can help me more
